Figure 6. MAX9223/MAX9224 Power-Up/Power-Down Sequence
Interconnect for LCDS typically has a differential imped-
ance of 110Ω. Use interconnect and connectors that have
matched differential impedance to minimize impedance
discontinuities.
Separate the logic and LCDS signals to prevent
crosstalk. A PCB or flex with separate layers for power,
ground, and signals is recommended.
Bypass each V
surface-mount ceramic 0.1µF and 0.01µF capacitors in
parallel as close to the device as possible, with the
smallest value capacitor closest to the supply pin.
The MAX9223/MAX9224 LCDS inputs and outputs
(SDO+/SDO-, SDI+/SDI-) are rated for ±15kV ESD pro-
tection using the Human Body Model. The Human Body
Model discharge components are C
1.5kΩ (Figure 7).
